URL: https://github.com/llvm/llvm-project/commit/3af82b3962c443d43edba1abb50a82fb3048999a DIFF: https://github.com/llvm/llvm-project/commit/3af82b3962c443d43edba1abb50a82fb3048999a.diff LOG: [clang-format] Add spaces around the Verilog implication operator (#71352) The Verilog implication operator `->` is a binary operator meaning either the left hand side is false or the right hand side is true. Previously it was treated as the C++ struct member operator. I didn't even know it existed when I added the operator formatting part. And I didn't check all the tests for all the operators I added. That is how the bad test got in.
